PREPARATION AND PROPERTIES OF THERMOELECTRIC MATERIALS

Abstract

Three methods of preparation of Mo and W tellurides were tried; only one of them, named preparation by chemical transport reactions, has been successfully used to yield small single crystals. The stability of these compounds is discussed and indications are given on the sintering process used to prepare barretts to allow electrical and thermal measurements. The lattice constants of MoTe2 and the optical energy gap were determined using small single crystals. Results are also available on the resistivity, Seebeck coefficient and diffusivity of MoTe2 and alloys of MoTe2 and WTe2. (Author)
